A certain financial services company uses surveys of adults age 18 and older to determine if personal financial fitness is chang

IgorLugansk [536]

Answer:

b) Then z(s) is in the rejection region for H₀. We reject H₀. The p-value is smaller than α/2

c)CI 95 % = ( 0.00002 ; 0.09998)

Step-by-step explanation: In both cases, the size of the samples are big enough to make use of the approximation of normality of the difference of the proportions.

Recent Sample

Sample size n₁ = 1000

Number of events of people with financial fitness more than fair

x₁ = 410

p₁ = 410/ 1000 = 0.4 then q₁ = 1 - p₁ q₁ = 1 - 0.4 q₁ = 0.6

Sample a year ago

Sample size n₂ = 1200

Number of events of people with financial fitness more than fair

x₂ = 420

p₂ = 420/1200 p₂ = 0.35 q₂ = 1 - p₂ q₂ = 1 - 0.35 q₂ = 0.65

Test Hypothesis

Null Hypothesis H₀ p₁ = p₂

Alternative Hypothesis Hₐ p₁ ≠ p₂

CI 95 % then significance level α = 5% α = 0.05 α/2 = 0.025

To calculate p-value:

SE = √ (p₁*q₁)/n₁ + (p₂*q₂)/n₂

SE = √ 0.4*0.6/1000 + 0.65*0.35/1200

SE = √ 0.00024 + 0.000189

SE = 0.021

z(s) = ( p₁ - p₂ ) / SE

z(s) = ( 0.4 - 0.35 )/0.021

z(s) = 0.05/ 0.021

z(s) = 2.38

We find p-value from z-table to be p-value = 0.00842

Comparing

p-value with α/2 = 0.025

α/2 > p-value

Then z(s) is in the rejection region for H₀. We reject H₀

CI 95 % = ( p₁ - p₂ ) ± 2.38*SE

CI 95 % = ( 0.05 ± 2.38*0.021 )

CI 95 % = ( 0.05 ± 0.04998)

CI 95 % = ( 0.00002 ; 0.09998)

CI 95 % does not contain the 0 value affirming what the hypothesis Test already demonstrate

The volume of a trapezoidal prism is 24 cubic units. It's height is 6 units, as labeled. What is the area of a trapezoidal base

scZoUnD [109]

Answer:

Area of trapezoidal base = 4 square units.

Step-by-step explanation:

We know that volume of a prism is known as :

$V = B \times h$

where B is Area of Base

and h is Height of prism

NOTE: Formula for Volume of a prism can be generalized as above irrespective of the type of base it has (base can be of type triangle, rectangle, square or trapezoidal etc).

Here, we are given that Base is trapezoidal.

h is 6 units and

Volume V is 24 cubic units.

And we have to find out the value of B.

Putting the above values in above formula:

$24 = B \times 6\\\Rightarrow B = \dfrac{24}{6}\\\Rightarrow B = 4 \text { square units}$
